A piicaton tiled May 24,

lie it known that I, Konmar J. S'roiins. a citizen ofthe Vnited States.and a resident of Trenton, eountwY of Mercer. titate of New Jersey,.have invented certain Improvements in Flexible Disk-Couplings, of whichthe following is a speeiiiration.

M v invention rela es to eertain improvements in tiexibie couplings otthe type in which a series of fiexihle disks are located one spiderbeing mounted on a driven shaft and the other spider being mounted onthe driving shaft.

The object ol Inj.' invention is to provide a coupling in whieh thedisks are made of canvas. or other 4l'ahrif:` and rubber. thearrangement being such that the strains to whirh the eoupling suhieetedwill he evenly distributed throughout the several dis s. making asuhstantial Coupling and one whieh will withstand the shocks and strainsplaced upon a eoupling` oi" this type. espeeially in automobile drivinggears.

in the aerompanying drawiru Figure 1 is a side view of a rouplinglillustrating mj.' invention:

Fig. :2 is an end view: and

Fig. 3 is a view showingl the .several disks detaehed and arranged sideh v side.

1 is a driving shaft. i2 is a driven shaft. f is a spider seeured to thedriving shaft and 4 is a spider secured to the driven shaft. The spider3 has three arms in the present instance. whieh are secured to the diskst3. G". (3", and (3" by bolts 7. S are three arms on the spider isecured to said disks by bolts 9. The arms of the spider #i alternatewith the arms of the spider'S. as clearl)v shown in Fig. 2.

Heretotore. it has been the general practiee to makeI these disks otleather. hut latelyv they have been made of a composition ot' canvas andrubber. There are, usnall \v several layers oi canvas. whieh have beenimpregnated with rubber. pressed. and vnltjanized into a solid disk.

ln a patent granted to li. J. Hardy. No. 1.172.988. dated February 1916.is shown. desrribed and elaimed the idea of making a solid disk of aplurality ot' separate layers of fabric sei-tired together with the warpSpecification of Letters Patent.

threads ot one laver at an angle to the warp threads ot' another laver.or layers. r`his is a praetieal watY ot making a very substantial disk.although it is wasteful and must be made b v an expert.

l find that l ean obtain verir good results h v making eaeh disk ot" apluralityv of layers ot' lahrie having their warp threads running in thesaine direetion, vuleanizing the ialirie. and then eutting the disk fromthe .strip of i'abrie. thus avoiding considerable waste. I then assemblethe disk iu sueh manner that the warps-fii'one disk (whieh are heavierthan the wetts) are arranged at an angle to those ol the other disks.

For instaure. in Fig. il. l have shown the t'oui' disk. t3. t3". t3".and (3 .separated and lined to indirate the direetion of the warps.These disks are all punehed from the same sheet of lahrie and by turningthem so that the wai-ps ol' the disk (3 will he at an angle ot' -i-idegrees to the warps ol the disk (i and the warps ol' the disk ti willhe at right anglegsl to the warps oi' the disk (3 and the wai-ps olA thedisk tl will be at right angles to the warps of th(l disk (S. then thewarps will be so distributed that the driving strain will lall evenl yon the entire series ol' disks. making a substantial coupling.

ll'hile l have shown a eoupliug made of tour disks. it will beunderstood that my invention ean be applied to a two-disk Coupling. lnthis event. the warps olE one disk will he arranged at an angle to thoseof the other disk. preferably at right angles.

ll'hen a eoupling is made of three disks. then the disks are so arrangedthat the warps ot' one disk will be at an angle to those ot' the othertwo disks. and if a, coupling' have more than four disks, then the diskswill he. arranged so that no two disks will have the Wai-ps running inthe same direction.

i elaiin:

1. The eonihination in a flexible ,-oupling, ot a driving and a drivenshaft; a spider mounted on eaeh shaft; and a .series ot' disks securedto eaeh spider. each disk heini: composed otl a plurality of layers offabric having their warp threads running in the same direetion, thedisks being so arranged that the costly and Htl warp threads of one diskwill be at a predetermined :ingle to those of the other section.

2. The combination in a Hexihle coupling, of :i drivingr and u drivenshaft; a spider mounted on each shaft: undy a series of four disksclamped to the arms of both spiders, enr-h disk being composed o'f :iplurality of layers of fabric having their Warp threads running,` in thesame direction, 'the disks be- 10 ing so arranged that the Warp threadsof the several disks are spaced at 45 degrees apartso that the strainsto which the coupling is subjected will be evenly distributed throughthe four disks.
